    I2c pic18f4420 eeprom

    i don't know , i thought that the code build he protocol itself , so i don't need to use the dedicated pins for i2c bus , i will use any pins. as we make it for atmel family without i2c protocol, wait ur reply

    [SOLVED] Pic 16f876a Pure Sinewave inverter

    pic16f876a based dc-ac inverter circuits dear friends, why we set PWMmax as 831 and how we can map the given sine wave LUT to a real time values like 20us,... duty cycle of the sine. and please , if any one can guide me in concept and how to construct the LUT. thanks best regards,
